This is (should be) the exact equivalent of the Cilia code in Swift:

• Types
  • Int, Int32, Int64, Float
• Variables
  • var x: Int = 42
  • var x = 42
  • let x = 42
  • var words: [String] = []
  • var names: Set<String> = Set()
  • var contactInfoForID: [String: ContactInfo] = [:]
• Functions
  • func multiply(_ a: Int, _ b: Int) -> Int { return a * b }
  • func print(_ a: ContactInfo) { ... }
  • func concat(_ a: String, _ b: String) -> String { return ... }
• Loops
  • for i in 1...10 { ... }
  • for i in 0..<words.count { ... }
  • for i in [5, 7, 11, 13] { ... }
  • for word in words { ... }
